i have netscape, mozilla and ie on the harddrive of all three computers with no problems at all. i had ie and netscape on every computer we've had since 1996 - i think that's 9 total. if netscape makes you nervous (i use the old version), use mozilla. it works for this, too.
after all, when you make web pages you don't know what it will look like in other browsers without checking. i've had some pages look great in ie that barely work in other browsers - which are 11% of my traffic.
